@victor-v-rad ,
We are facing the same issues after we migrated the data's from M1.7 to M2.1.6.
and also unable to view the customers in back office and unable to register the new users in front end.
We are getting the below error and we got the message successfully migrated.

Fatal error: Uncaught Error: Call to undefined method Magento\Eav\Model\Entity\Attribute\Backend\ArrayBackend\Interceptor::getAllOptions() in D:\xampp\htdocs\magento21\vendor\magento\module-customer\Model\AttributeMetadataConverter.php:66 Stack trace: #0 D:\xampp\htdocs\magento21\vendor\magento\module-customer\Model\Metadata\CustomerMetadata.php(77): Magento\Customer\Model\AttributeMetadataConverter->createMetadataAttribute(Object(Magento\Customer\Model\Attribute)) #1 D:\xampp\htdocs\magento21\vendor\magento\module-customer\Model\Metadata\CustomerMetadata.php(109): Magento\Customer\Model\Metadata\CustomerMetadata->getAttributeMetadata('default_blog_ca...') #2 D:\xampp\htdocs\magento21\vendor\magento\module-customer\Model\Metadata\CachedMetadata.php(82): Magento\Customer\Model\Metadata\CustomerMetadata->getAllAttributesMetadata() #3 D:\xampp\htdocs\magento21\vendor\magento\module-customer\Ui\Component\Listing\AttributeRepository.php(66): Magento\Customer\Model\Metadata\CachedMetadata->getAllAttributesMetadata() #4 D:\xampp in D:\xampp\htdocs\magento21\vendor\magento\module-customer\Model\AttributeMetadataConverter.php on line 66
